Other claims from this paper (8)
- Association Only helvolic acid production in rice sheaths correlated with fungal virulence.
- Intervention effect Infection with low-toxin, least-virulent S. oryzae strongly increased rice sheath endophyte diversity relative to healthy sheaths.
- Intervention effect Virulent S. oryzae isolates did not affect rice endophyte diversity.
- Intervention effect Virulent S. oryzae isolates strongly shifted rice endophyte species composition.
- Observation B. cereus dominated the endophyte community of healthy rice plants.
- Observation B. cereus was enriched in rice sheath lesions made by low-virulence S. oryzae.
- Observation Helvolic acid producers eliminated B. cereus from the rice sheath endosphere.
- Mechanism The authors infer that S. oryzae produces antibiotics to overcome antagonistic rice endophytes and infect sheaths.
